The MASTER_SITE download.crossroads.io no longer exists and libxs has
been marked BROKEN because the distfile is unfetchable. Change the
port to USE_GITHUB=yes and unmark BROKEN. Comparing the old and new
tarballs does not reveal any changes to the source. The new tarball
now contains .gitignore, .hgeol, and README.asciidoc. The new tarball
is missing the man pages and html docs, Changelog, and the files
generated by the autotools. The latter requires the addition of
USES=autoreconf, which in turn requires patches to be applied to some
files at an earlier stage. The missing documentation files are
generated by the build.
While here, switch to INSTALL_TARGET=install-strip to silence a stage-qa
warning.

Crossroads I/O ("libxs") is a library for building scalable and high
performance distributed applications. It fits between classic BSD sockets,
JMS/AMQP-style message queues, and enterprise message-oriented middleware.
Crossroads I/O extends the standard socket interfaces with features
traditionally provided by specialised messaging middleware products,
providing an abstraction of asynchronous message queues, multiple messaging
patterns, message filtering (subscriptions), seamless access to multiple
transport protocols, and more.
Crossroads I/O provides a native C API for applications. Support for many
more languages is provided by the community through language bindings which
can be found at the Crossroads website.
